Description
Alphanumeric LCD display supplied with the voltage of 5V with the blue backlight.
Management
The display can be controlled in the following modes:
- 8-bit without busy flag read for transmission of the desiredeight data bus lines and two control lines (RS, E - RW is connected to ground).
- 8-bit with busy flag read for transmission of the desiredeight data bus lines and three control lines (RS, E, RW).
- 4-bit with busy flag readfor transmission of the desired four lines of data bus and three control lines(RS, E, RW).
- 4-bit without busy flagfor transmission of the desired four lines of data bus and two control lines (RS, E - RW is connected to ground)).
The most frequently selected method of communication is the mode 4-bit without busy flag read. Sending a half-byte allows you to save valuable I/O microcontroller - only four data lines are beign used (8-bit captured eight of them). No busy flag read introduces the need to use software delays, but allows you to save even a single line - R/W. Pins can be connected on a permanent basis to the ground, because the data will be transported to the displayin one direction only.
